Detailed Description

extract a cells or points from a dataset that have values within a set of thresholds.

vtkExtractSelectedThresholds extracts all cells and points with attribute values that lie within a vtkSelection's THRESHOLD contents. The selecion can specify to threshold a particular array within either the point or cell attribute data of the input. This is similar to vtkThreshold but allows mutliple thresholds ranges. This filter adds a scalar array called vtkOriginalCellIds that says what input cell produced each output cell. This is an example of a Pedigree ID which helps to trace back results.

Member Function Documentation

virtual const char* vtkExtractSelectedThresholds::GetClassName (  )  [virtual]

Reimplemented from vtkExtractSelectionBase.

static int vtkExtractSelectedThresholds::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkExtractSelectionBase.

virtual int vtkExtractSelectedThresholds::IsA ( const char *  name  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkExtractSelectionBase.

static vtkExtractSelectedThresholds* vtkExtractSelectedThresholds::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkExtractSelectionBase.

void vtkExtractSelectedThresholds::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkExtractSelectionBase.

static vtkExtractSelectedThresholds* vtkExtractSelectedThresholds::New (  )  [static]

Constructor

Reimplemented from vtkDataObjectAlgorithm.

static int vtkExtractSelectedThresholds::EvaluateValue ( vtkDataArray scalars,
vtkIdType  id,
vtkDoubleArray lims 
) [static]

Function for determining whether a value in a data array passes the threshold test(s) provided in lims. Returns 1 if the value passes at least one of the threshold tests.

static int vtkExtractSelectedThresholds::EvaluateValue ( vtkDataArray scalars,
vtkIdType  id,
vtkDoubleArray lims,
int *  AboveCount,
int *  BelowCount,
int *  InsideCount 
) [static]

Function for determining whether a value in a data array passes the threshold test(s) provided in lims. Returns 1 if the value passes at least one of the threshold tests. Also returns in AboveCount, BelowCount and InsideCount the number of tests where the value was above, below or inside the interval.
